【摘要】 对日照烟煤和京西无烟煤在不同温度下制得半焦进行了工业分析和硫的元素分析,研究了不同煤种制得半焦中挥发分、灰分、固定碳以及硫元素含量随制备温度不同的变化趋势,并在管式沉降炉中进行了半焦的燃烧实验,分别计算了不同半焦的燃烧动力学参数.更多还原

【Abstract】 The preliminary analysis and ultimate analysis of sulfur were done of different semi-cokes produced from Rizhao bituminous coal and Beijing anthracite at different temperatures. The tendency of the contents of volatile,ash,fixed carbon and sulfur of different semi-cokes which can change with different preparation temperatures was also studied. Then the combustion experiments with semi- cokes in the drop-tube furnace system was carried out,and the kinetic parameters of different semi-cokes were calculated.更多还原
